I'm new to bitcoin although I knew about it in early 2015. I regreted not to pay attention to it because there are many opportunities of making money. On the other hand, when I researched for economy, banking, trading...I was going to know that BTC is an important crytocurrency. Now around me many people buy/sell/trade or using BTC in their life.
If someone is interested in darknet, BTC is the way to purchase. But I don't know much about it and I have no demand about things in darknet. Just trying to earn BTC to invest.

I save it for both. I think it will be a good way to invest. On the other hand, saving BTC may be the way to change something, like upgrading our life. 

In this forum you can join a signature campaign or provide your service to get BTC. Do you have some skills like design, programing...? Some people get paid from cloud mining but there are many scams so be carefull.
In my town there are some coffee shops which accept BTC. You can do it if you are able to.

1. Signature Campaign (in this forum only)
2. Cloud mining (many scams)
3. Mining (need to invest hardware to mine)
4. Become a freelancer, provide your service and get paid (on freelance.com, elance...)
